Abstract
EUKARYOTIC cells are thought to contain a framework of fibrillar proteins—or ‘cytoskeleton’—which is a basis for their shapes and movements. To understand this structure it is necessary to know both the properties of the component proteins and the way they are linked together. Actin and spectrin are two such structural proteins: actin is familiar for its part in muscle contraction, but is present partly as microfilaments1,2 throughout the cytoplasm of most cells; spectrin is the major protein of red blood cell membranes and makes up a network on the cytoplasmic surface3,4.
